Objective: To identify the COVID-19 pandemic impact on well-being/mental health, coping strategies, and risk factors in adolescents worldwide.

Method: This study was based on an anonymous online multi-national/multi-language survey in the general population (representative/weighted non-representative samples, 14-17 years of age), measuring change in well-being (World Health Organization-Five Well-Being Index [WHO-5]/range = 0-100) and psychopathology (validated composite P-score/range = 0-100), WHO-5 <50 and <29, pre- vs during COVID-19 pandemic (April 26, 2020-June 26, 2022). Coping strategies and 9 a priori- defined individual/cumulative risk factors were measured.

Background: The hypothesis that not only diagnosed diabetes (DM), but also milder dysglycemia may affect the development of atherosclerosis still requires further study. In our population-based study, we aimed to evaluate the impact of prediabetic state on preclinical atherosclerosis and whether it may affect the cardiovascular risk (CVR) in the general population.

Methods: The analysis was a part of the Bialystok PLUS cohort study and represented a random sample of Bialystok (Poland) residents aged 20-79 years at the time of sampling (July 2017-January 2023).

Article Synopsis
  • Multiple sclerosis (MS) is a chronic disease affecting the central nervous system, characterized by inflammation and damage to nerve fibers due to the loss of myelin.
  • Research highlights the varying roles of interleukins, where some, like IL-10, have protective effects, while others, such as IL-6, can worsen inflammation.
  • Findings suggest that interleukins could be key in developing new MS treatments and identifying prognostic markers, with specific therapies, such as anti-IL-12p40, showing positive results in patients.

Article Synopsis
  • The COH-FIT study is a large, multi-country survey aimed at identifying factors affecting wellbeing and mental health outcomes during the COVID-19 pandemic, involving a representative sample of 121,066 adults.
  • Researchers analyzed both modifiable (like coping strategies and pre-pandemic stress) and non-modifiable factors (such as age, gender, and socioeconomic status), finding significant negative effects on wellbeing and psychopathology scores during the pandemic.
  • The study identified 15 modifiable and 9 non-modifiable risk factors, alongside 13 modifiable and 3 non-modifiable protective factors, emphasizing the importance of social support and coping strategies in mental health outcomes.

Article Synopsis
  • There is a lack of comprehensive international studies examining multidimensional mental health and wellbeing before and during the COVID-19 pandemic, particularly identifying at-risk groups and effective coping strategies.
  • The COH-FIT survey, conducted from April 2020 to June 2022 in 30 languages, assessed changes in well-being and psychopathology among over 121,000 participants, revealing significant declines in mental health during the pandemic.
  • Key findings indicated that certain demographics, such as young adults and people in low-income countries, were particularly affected, while coping strategies like exercise, internet use, and maintaining social contacts emerged as the most effective for managing stress.

The aim of the study was to investigate the relation between thyroid autoimmunity (TAI), reflected as the presence of thyroid peroxidase antibodies (TPOAb), and parameters of ovarian reserve in women with type 1 diabetes (T1DM) and polycystic ovary syndrome (PCOS). We studied 83 euthyroid women with T1DM (age - 26 ± 5 years, BMI - 24 ± 3 kg/m) - 12 with PCOS and positive TPOAb (PCOS + TPOAb), 29 with PCOS with negative TPOAb (PCOS + noTPOAb), 18 without PCOS with positive TPOAb (noPCOS + TPOAb), 24 without PCOS with negative TPOAb (noPCOS + noTPOAb). Serum concentrations of anti-Müllerian hormone (AMH), sex hormones, TSH, thyroid hormones and TPOAb were assessed.

Considering the frequency and severity of olfactory disorders associated with SARS-CoV-2 infection, attention to the olfactory loss has expanded. The aim of our study was to assess of smell disturbances 6 months after COVID-19. The study population consisted of 2 groups: 196 Post-COVID-19 patients who were hospitalized because of COVID-19, control sample-130 patients without reported smell disorders from general population-Bialystok PLUS study.

Objectives: Multiple sclerosis (MS) is a chronic autoimmune inflammatory disease. Patients with relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) differ in their responses to treatment; therefore, the correct diagnosis of the particular type of MS is crucial, and biomarkers that can differentiate between the forms of MS need to be identified. The aim of this study was to compare the levels of inflammatory parameters in serum samples from patients with RRMS and SPMS.

Many studies indicate an important role of microglia and their cytokines in the pathophysiology of multiple sclerosis (MS). Microglia are the macrophages of the central nervous system (CNS). They have many functions, such as being "controllers" of the CNS homeostasis in pathological and healthy conditions, playing a key role in the active immune defense of the CNS.
